A6283
LINEAR INTEGRATED CIRCUIT
4.6W DUAL AUDIO POWER
AMPLIFIER
DESCRIPTION
UTC A6283 is an audio power IC with built-in two channels
developed for portable radio cassette tape recorder.
Because of the parts reduction and sip (Single In line
Package), space merit is remarkable.
Thermal shut down protection circuit is built in.
FEATURES
* High Power
* POUT = 2.5W/CH (Typ.)
: (VCC = 9V, RL = 4Ω, f = 1kHz, THD = 10%)
POUT = 4.6W/CH (Typ.)
: (VCC = 12V, RL = 4Ω, f = 1kHz, THD = 10%)
* Low popping noise at power ON
* Small Quiescent Current
: IQ = 19mA (Typ.), (VCC = 9V, VIN = 0)
* Soft Clip
* Built-in thermal shut down protection circuit
* Best for supply voltage 9V, 12V

LINEAR INTEGRATED CIRCUIT
APPLICATION INFORMATION AND APPLICATION METHOD
1. ADJUSTMENT OF VOLTAGE GAIN
The voltage gain GV is obtained as follows by R1, R2 and RF in Fig.1.
GV = 20 log
RF+R1+R2
RF+R1
When RF = 0
GV = 56dB (Typ.)
When RF = 82Ω GV = 45dB (Typ.)
By increasing RF, reduction of GV is possible, However, since the feedback increase is liable to produce oscillation, it
is recommended to use this at 40dB or over.

2. THERMAL SHUT-DOWN CIRCUIT
The thermal shut-down circuit is built in for the purpose of preventing the destruction of IC due to the abnormal
temperature rise when the heat radiation is insufficient.
